Texas A&M QB and Heisman Trophy winner Johnny Manziel has filed a lawsuit claiming trademark infringement on the Johnny Football name, The Southeast Texas Record reported.

Manziel’s corporation, JMAN2 Enterprises LLC, filed suit against Eric Vaughn on Feb. 15, claiming that Vaughn was selling shirts that said, “Keep Calm and Johnny Football.” The corporation is asking for injunctive relief for the sale of the shirts and damages associated with it.

Interestingly, ESPN’s Darren Rovell reported that Texas A&M received an NCAA ruling that said student athletes can keep financial earnings as a result of legal action. However, JMAN2 can’t profit off Manziel until the QB leaves school or his eligibility expires, Rovell notes.

Manziel rose to fame as a freshman this past season for Texas A&M, leading the Aggies to a 11-2 record, which included a win over No. 1 Alabama in Tuscaloosa. Manziel turned that success into becoming the first ever freshman Heisman Trophy winner.
